Installing & Using Gnome-Do
GNOME Do (Do) is an intelligent launcher tool that makes performing common tasks on your computer simple and efficient. Do not only allows you to search for items in your desktop environment (e.g. applications, contacts, bookmarks, files, music), it also allows you to specify actions to perform on search results (e.g. run, open, email, chat, play). Want to send an email to mom? Simply type “email mom.” Want to listen to some music? Simply type “play beatles.” Do provides instantaneous, action-oriented desktop search results that adapt to reflect your habits and preferences. For example, if you use Firefox web browser often, typing “f” in Do will launch it. Or, if you visit The New York Times webpage often, Do will open it if you simply type “nyt.” Unlike other search tools that present search results as flat, homogeneous lists, Do provides familiar graphical depictions of search results that assure you that your intent is being realized correctly; searching for “mom” will show a picture of mom, and searching for “beatles” will show a Beatles album cover. Do has many more powerful and exciting capabilities that must be seen to be appreciated.
Installing & Using TimeVault in Ubuntu/Debian
TimeVault is a simple front-end for making snapshots of a set of directories. Snapshots are a copy of a directory structure or file at a certain point in time. Restore functionality is integrated into Nautilus - previous versions of a file or directory that has a snapshot can be accessed by examining the properties and selecting the ‘Previous Versions’ tab.
Snapshots are protected from accidental deletion or modification since they are read-only by default. The super-user can delete intermediate snapshots to save space, but files and directories that existed before or after the deletion will still be accessible.
A snapshot is a copy of a directory at a certain point in time. Snapshots don’t use space for the files that haven’t changed but instead simply increment the link count for them. On Linux, when a file is deleted, the link count is decremented, but it isn’t actually removed until the link count hits zero.
Only files are hard-linked this way. Directories have to be recreated for technical reasons (since a hard-link is actually the file it points to, you would find yourself in a completely different path if directories were hard-linked).
How to turn off Firefox 3’s “awesome bar”
In Firefox 3, the Location Bar received a number of improvements. Among those improvements was the move to a XUL richlistbox widget for the auto-complete dropdown. This allowed styled URL/title information, favicons, and highlighted match information. This preference determines how many entries should appear (at most) in the dropdown. Many find Firefox 3’s “awesome bar” quite annoying. Luckily this is easy to disable.
First, in the address bar type: “about:config” (without the quotes).
In the about:config search bar type: Browser.urlbar.maxRichResults
The default value is set to 12. If you set this interger to 0, nothing will display in the “awesome bar” any longer.
Import PeerGuardian Blocklists into Ktorrent & Deluge
Many lovers of PeerGuardian are out there, and some just happen to use linux. Luckily we have bit torrent clients that support PeerGuardian blocklists directly in the client, rather than affecting our entire internet connection. This is a rather simple prodcedure in both cases of Ktorrent and Deluge.
Note: Blocklists are not a fool proof protection and can come with their own problems. Please read up on the effectiveness of blocklists. That being said, every little bit helps.

Install IpodLinux on your iPod
iPodLinux is an open source venture into porting Linux onto the iPod (http://www.apple.com/ipod/). So far, they have successfully ported a customized uClinux (http://www.uclinux.org) kernel to the iPod, and written a simple user interface for it dubbed podzilla. Additional applications and modules have been written, adding many capabilities not found in Apple’s firmware. iPodLinux currently works on all iPod generations with the exception of the 2nd/3rd generation iPod nano, 6th generation iPod classic, all iPod shuffles and the iPod Touch. Donations always help when it comes to supporting new hardware. Progress can be tracked on the Project Status.
How to use lzma for compression
